Description

  The present invention relates to a biological information collecting system including a biological information measuring device that measures biological information and a portable data collector that collects measurement results of biological information measured by the biological information measuring device.

  At present, POCT (Point of Care Testing) in which examination is performed in close proximity to a patient in a medical field is becoming important for improving the quality of diagnosis. In addition, biometric information measuring instruments and test pieces for carrying out POCT are being improved at a low price and high performance every day, and it is becoming an environment where patients themselves can easily purchase measuring instruments. Accordingly, self-measurement represented by SMBG (Self-Monitoring of Blood Glucose) has been carried out in POCT.

  In this way, in an environment where self-measurement is performed, diagnosis is performed in the medical field based on the measurement result of the patient performing self-measurement. Therefore, there is a need to collect measurement results from each patient efficiently and without error.

  Therefore, a biological information measuring instrument equipped with a wireless communication function for collecting data efficiently is becoming widespread. As a result, the nurse collects the measurement results from the necessary biological information measuring device even from a position several meters away, using a portable data collector represented by PDA (Personal Digital Assistant) equipped with a wireless communication function. It is possible.

  When wireless communication is used in this way, a device that uses the same type of wireless communication as that of the biological information measuring device that is the target of acquiring the measured biological information within the wireless communication range of the portable data collector that is the master If it exists, the device and the portable data collector will be connected. Therefore, it is necessary to take measures not to collect measurement results from a device different from the target device.

Therefore, as a conventional technique, an identification address for each device is registered in advance in the portable data collector in association with a name that can be determined by the nurse (hereinafter referred to as a device name) and communicates with the registered device. Sometimes, a device that displays a device name associated on a screen of a portable data collector from an identification address acquired by wireless communication is disclosed (for example, see Patent Document 1).
JP 2002-281041 A

  In the conventional technique, in an environment where a plurality of nurses use a plurality of portable data collectors, a single biometric information measuring device may be registered with a different device name for each portable data collector. . In that case, when the nurse who uses the portable data collector is replaced, there is a problem that it is difficult to specify the target biological information measuring device based on the registered device name.

  Therefore, an object of the present invention is to provide a biological information collecting system that can easily specify a target biological information measuring device based on a registered device name.

  In order to achieve the above-described object, the biological information collecting system of the present invention includes a biological information measuring device that measures biological information, and a portable data collector that collects biological information measured by the biological information measuring device. In the configured biological information collection system, the biological information measuring device includes a device name changing unit that sets a device name of the biological information measuring device when receiving a device name change command from the portable data collector, The biometric information and the changed device name are associated with each other and transmitted to the portable data collector.

  The biological information collection system of the present invention includes a device name changing unit that changes the device name transmitted from the portable data collector in the biological information measuring device, and registers the device name changed by each portable data collector. Therefore, the target biological information measuring device can be easily specified based on the registered device name.

  Embodiments of a biological information collecting system according to the present invention will be described below in detail with reference to the drawings.

(Embodiment 1)
FIG. 1 shows a block diagram of the biological information collecting system of the present invention. As shown in FIG. 1, the biological information collecting system includes a biological information measuring device 110 and a portable data collecting device 120. Furthermore, the biological information measuring device 110 includes a biological information measuring unit 111, a first wireless communication unit 112, an identification address holding unit 113, a device name holding unit 114, a device name changing unit 115, and a measuring device control unit. 116. The portable data collector 120 includes a second wireless communication unit 121, a device name management unit 122, a data management unit 123, a command generation unit 124, and a data collector control unit 125.

  FIG. 2 is a diagram showing an outline of the biological information collection system. In the example illustrated in FIG. 2, the three biological information measuring devices 110 a to 110 c and the portable data collector 120 perform wireless communication. The portable data collector 120 includes a user input unit 126 and a display unit 220 as external interfaces. The biometric information measuring devices 110a to 110c include a display unit 200 and a user input unit 201 including a plurality of buttons as external interfaces, and hold a test piece 210 for measuring biometric information.

  In this embodiment, the example applied to the blood glucose meter which measures the blood glucose level of the blood spotted on the test piece 210 as biological information measuring device 110a-110c is shown. These biological information measuring devices 110a to 110c are portable blood glucose meters that are battery-driven and have a size that can be waited with one hand.

  The display unit 200 of the biological information measuring devices 110a to 110c is a display using either a segment method or a dot matrix method. The user input unit 201 is a push button type button, and includes at least a button having a function of changing data displayed on the display unit 200 and a button having a function of determining.

  The biological information measuring unit 111 is a block that measures the blood sugar level of blood spotted on the test piece 210 and outputs it as biological information. The biological information measuring unit 111 attaches a disposable unused test piece 210 that performs an electrochemical reaction to the biological information measuring device 110, and drops blood on the test piece 210. Detects that blood is spotted on the test piece 210 and measures the blood glucose level from the components in the blood spotted on the test piece 210.

  FIG. 3 shows the configuration of the biological information measuring unit 111. The biological information measuring unit 111 includes a connector 320, an operational amplification circuit 330, a feedback resistor 340, an A / D (Analog to Digital) conversion circuit 350, an arithmetic circuit 360, a storage unit 370, and a reference potential 380. Composed. The test piece 210 used for the measurement is a disposable and electrochemical reaction type, and includes a working electrode 211, a counter electrode 212, and a reactant 213 made of an enzyme, a mediator, or the like.

  The operation of the biological information measuring unit 111 configured as described above will be described in detail. The connector 320 is an insertion port for inserting the test piece 210 and includes an electrode 321 and an electrode 322. When the test piece 210 is inserted into the connector 320, the electrode 321 contacts the working electrode 211, and the electrode 322 contacts the counter electrode 212. With the test piece 210 inserted into the connector 320, the user drops blood on the reactant 213 of the test piece 210. When blood is spotted on the reactant 213, the reactant 213 dissolves in the blood and the enzyme reaction proceeds.

  Next, a voltage is applied to the working electrode 211 and the counter electrode 212 through the electrode 321 in contact with the working electrode 211 of the test piece 210 and the electrode 322 in contact with the counter electrode 212 of the test piece. When a voltage is applied, a current correlated with the blood glucose concentration in the blood flows through the feedback resistor 340 to the test piece 210. The non-inverting input terminal 331 of the operational amplifier 330 is connected to the reference potential 380, and the operational amplifier 330 controls to keep the non-inverting input terminal 331 and the inverting input terminal 332 at the same potential. Therefore, a voltage obtained by adding the potential of the drop due to the current of the feedback resistor 340 to the reference potential 380 is generated at the output terminal 333. By this action, a voltage proportional to the current flowing through the test piece 210 is generated at the output terminal 333, and current-voltage conversion can be performed. The voltage generated at the output terminal 333 is converted into a digital value by the A / D conversion circuit 350. Then, the A / D conversion circuit 350 transmits the converted digital value to the arithmetic circuit 360.

  The arithmetic circuit 360 calculates a blood glucose concentration that is a blood glucose level in the blood from the received digital value. In order to calculate the blood glucose level, for example, the following processing is performed. Two constant current sources that generate currents corresponding to a low blood glucose concentration and a high blood glucose concentration are connected to the connector 320 in advance, and from each A / D conversion value, a calibration curve that is a primary conversion formula of a current value and a digital value This is obtained by the arithmetic circuit 360. The slope a and the intercept b of the calibration curve are information for associating the digital value transmitted from the A / D conversion circuit with the blood glucose level, and this calibration curve is stored in a control program in the biological information measuring instrument. deep. Therefore, the arithmetic circuit 360 calculates the blood glucose level by applying the digital value received from the A / D conversion circuit 350 to the calibration curve.

  Furthermore, the biological information measuring unit 111 includes a time acquisition unit 361. The time acquisition unit 361 is a time management function using a real time clock. When the time acquisition unit 361 receives the time acquisition request, it returns the current time in a format in which the year, month, day and hour can be determined. The time management function can also be realized by time-converting the count value obtained from the counter using the system clock. The arithmetic circuit 360 transmits a time acquisition request to the time acquisition unit 361 after the calculation of the blood sugar level. Then, two data of the current time acquired as a response to the time acquisition request and the calculated blood glucose level are transmitted to the storage unit 370 as measurement results.

  The storage means 370 stores the received measurement result by adding a management ID of a serial number that can be determined to be related to the stored past measurement result. The storage unit 370 is a rewritable memory represented by an EEPROM (Electrically Erasable Programmable Read-Only Memory), and it is an essential condition that the stored data does not disappear even when the biometric information measuring device 110 is turned off. . The storage means 370 has a predetermined number that can be stored. When the number that can be stored is exceeded, the oldest past measurement result is deleted and a new measurement result is stored. Further, when receiving the measurement result transmission instruction, the storage unit 370 transmits the measurement result to the first wireless communication unit 112 according to the instruction content.

  The biological information measuring unit 111 may perform immunoassay using a method of optically detecting an antigen-antibody reaction using chromatographic development when blood is spotted on a chromatographic test piece. The measurement may be performed using a non-invasive measurement method that does not use the piece 210.

  The first wireless communication unit 112 may be realized by a standardized method typified by Bluetooth (registered trademark), UWB (Ultra Wide Band), ZigBee, or Wibre, and may be used for each country. It may be realized by a method using wireless communication of a unique method using a different frequency band. In this embodiment, a method using Bluetooth (registered trademark) is used.

  When the first wireless communication unit 112 receives an inquiry, which is a device search command, from the outside, the first wireless communication unit 112 returns an identification address allocated by the biological information measuring device 110 and a device name indicating the biological information measuring device 110. In Bluetooth (registered trademark), an identification address and a device name are exchanged between devices that have been inquired by LMP (Link Manager Protocol). An identification address acquisition request is transmitted to the identification address holding unit 113. Also, a device name acquisition request is transmitted to the device holding unit 114 to acquire the device name. Further, upon receiving a connection request command from the outside, the first wireless communication unit 112 establishes a connection in accordance with the Bluetooth (registered trademark) standard. After the connection, communication is realized with a corresponding Bluetooth (registered trademark) communication profile. After connection, at least the received command is transmitted to the measuring instrument control unit 116, the received measurement result is transmitted to the connection partner, and the received device name measurement result is transmitted to the connection partner. And send to the other party.

  When the first wireless communication unit 112 is realized by a method using unique wireless communication, a protocol part corresponding to a device search command, a protocol part corresponding to a connection request command, and a communication protocol after connection There is a need to create a way to realize the part.

  The identification address holding unit 113 includes storage means that can be written at least once. The storage means of the identification address holding unit 113 is an EEPROM or a FLASH ROM. At the time of shipment of the biological information measuring device 110, the writing of the identification address assigned to the biological information measuring device 110 is completed in the storage means of the identification address holding unit 113. There is no need to rewrite the identification address after the biological information measuring instrument 110 is shipped. Further, when receiving the identification address acquisition request from the first wireless communication unit 112, the identification address holding unit 113 acquires the identification address from the storage unit of the identification address holding unit 113 and sends it to the first wireless communication unit 112. Send.

  The device name holding unit 114 manages two device names. For this reason, storage means capable of storing two device names is provided. One device name of the two device names is a fixed initial device name. The other device name is a user device name that can be changed.

  The initial device name is set in common in the biological information measuring instrument 110 manufactured with at least the same model number. Further, the user device name is a common measuring device identification code indicating that it is the biological information measuring device 110, a unique user identification code indicating the user of the biological information measuring device 110, and the biological information measuring device 110. Corresponding to device name naming rules in at least three types of combinations. The measuring instrument identification code and the user identification code are each expressed with alphanumeric characters after being fixed to a predetermined data length. The user identification code is a patient ID in the hospital. By providing the measuring device identification code, it can be used to determine whether or not the biological information measuring device 110 is based on the user device name. Further, by providing the user identification code and the user name, it is possible to determine when the same user name exists.

  Table 1 shows an example showing the relationship between the above two device names and the biological information measuring device. No. 1-No. In the three biometric information measuring devices of No. 3, two device names are respectively represented. Since the initial device name is common in the biological information measuring device, it is all “GlucoseMeter”. Although the user device name is different for each biometric information measuring device, the measuring device identification code of the user device name is common, so that all the measuring device identification codes are “GM”.

  A storage means for storing two device names will be described. Since the initial device name does not need to be rewritten, it may be stored in advance in a non-rewritable ROM area without using a rewritable storage medium. Since the user device name needs to be rewritten, a rewritable storage medium such as an EEPROM is used. At this time, the area necessary for managing the user device name may be within a few dozen bytes to 100 bytes. However, when it is assumed that the maximum data length of the user device name is required to be 100 bytes or more, an area corresponding to the maximum data length is secured.

  When receiving a device name acquisition request from the first wireless communication unit 112, the device name holding unit 114 selects one of the two device names, and selects the selected device name as the first wireless communication unit. Reply to 112. The method for selecting one of the two device names is that if a user device name is set, the user device name is the device name, and if no user device name is set, the initial device name is the device name. And

  When receiving the command received from the first wireless communication unit 112, the measuring instrument control unit 116 performs command analysis on the received command. Next, each process is executed from the result of command analysis.

  First, the command will be described. The command structure is shown in FIG. The command format 400 includes a combination of a command identifier 410 and a command parameter 420. The command identifier 410 sets a character code assigned to each command with a fixed data length of several bytes. The command parameter 420 is a variable length data and sets necessary parameters for each command. If the command does not require a parameter, the command parameter is not set. There are at least two commands, ie, a measurement result request command 401 and a device name change command 402. For example, the case where the command identifier 410 has a fixed length of 2 bytes will be described. The measurement result request command 401 includes “RD” of the command identifier 411 and the measurement result request parameter of the command parameter 421, and the device name change command 402 includes “CH” of the command identifier 412 and the device name of the command parameter 422. Consists of. The measurement result request parameter specifies the transmission content of the measurement result, and at least three types of transmission, that is, transmission of all stored measurement results, transmission of only the latest measurement results, and transmission of measurement results that have not been transmitted Is a parameter that can be classified, and is set with a 1-byte ASCII code.

  Next, command analysis and each process will be described. In the command analysis, it is analyzed whether or not the command identifier 410 of the command format 400 corresponds. Each process executes a process for each command from the result of command analysis. If the command received from the result of the command analysis is the measurement result request command 401, a measurement result transmission instruction is transmitted to the biological information measuring unit 111 together with the measurement result request parameter 421.

  If the command received from the result of the command analysis is a device name change command, a device name change instruction is transmitted to the device name change unit 115 together with a device name 422 as a parameter. Then, it waits for a reply of the device name change result from the device name changing unit 115. Upon receiving the device name change result from the device name changing unit 115, the measuring instrument control unit 116 transmits the device name change result to the first wireless communication unit 112. On the other hand, if the command received from the result of the command analysis is an unsupported command, it transmits to the first wireless communication unit 112 that it is an unsupported command.

  When the device name change unit 115 receives the device name change instruction, the device name change unit 115 checks whether or not the new device name received simultaneously with the device name change instruction corresponds to the device name naming rule. If the device name naming rule is not supported, an error is transmitted as a device name change result to the measuring instrument control unit 116. If the device name naming rule is supported, the user device name is stored after all the storage areas related to the user device name in the device holding unit 114 are initialized. And it transmits to the measuring device control part 116 that it was able to be changed normally as a device name change result. The above is the description of the biological information measuring device 110.

  Next, the portable data collector 120 will be described. The second wireless communication unit 121 has a wireless communication function capable of communicating with the first wireless communication unit 112 of the biological information measuring device 110. Similar to the first wireless communication unit 112, the wireless communication function may be realized by a standardized method represented by Bluetooth (registered trademark), UWB, ZigBee, or Wibre, and is defined for each country. It may be realized by a method using wireless communication of a unique method using a usable frequency band. However, the same method as that of the first wireless communication unit 112 is adopted. The wireless communication between the second wireless communication unit 121 and the first wireless communication unit 112 is performed by the portable data collector 120 as a master and the biological information measuring device 110 as a slave.

  The display unit 220 of the portable data collector 120 is configured by a dot matrix type display. The display unit 220 displays the received display content on the display. The user input unit 126 includes a plurality of push buttons. When an input acceptance start instruction is received, button input is detected. When the input of the button is detected, processing corresponding to the content of the button input by the user is performed. When it is detected from the combination of the input of a plurality of buttons that the input is completed, the value input to the other party who transmitted the input acceptance start instruction is returned. In addition, the input value is transmitted to the display unit 220 as display content. The user input unit 126 may be a touch panel type input unit integrated with the display unit 220. In that case, the display unit 220 further includes a touch panel sensor.

  The device name management unit 122 includes a rewritable storage area. The storage area is secured by an HDD (Hard Disc Drive), Flash ROM, EEPROM, or the like. Further, it may be secured on a removable memory represented by an SD card. In that case, it is necessary to provide the portable data collector 120 with a dedicated interface for accessing the memory to be used. Further, the device name management unit 122 may use an existing database for device name management. When a database is used, device name management is performed at high speed. However, since a large amount of memory is used in the portable data collector, is the database used based on the overall memory usage capacity? It is good to judge.

  FIG. 5 shows device name management data 500 for one device name. The device name management data 500 includes device name data 510 and identification address data 520 that is associated with the device name data 510.

  Next, detailed contents of the device name management data 500 will be described. The device name data 510 is used by the device name management unit 122 for the four elements of the user device name 512, the identification address information ID 521 indicating the identification address data 520, the registration date and time 513, and the inquiry date and time 514. It is composed of five elements with a device name management ID 511 that is the ID of the device. The registration date and time 513 and the inquiry date and time 514 are set by acquiring data from the clock function in the portable data collector 120 to the date and time. Therefore, the portable data collector 120 has a clock function capable of measuring the current time obtained by calculating a real-time clock or a system clock.

  The identification address data 520 is associated with the device name data 510 in three elements: a device name management ID 511, a registration number 522 that is the registration number of the identification address, and a plurality of identification addresses 523 corresponding to the registration number 522. It is composed of four elements with identification address information ID 521 which is an ID for this purpose.

  By configuring the device name management data 500 with device name data 510 and identification address data 520, a plurality of identification addresses 523 can be managed for the user device name 512. As a result, it is possible to cope with the case where the user has a plurality of biological information measuring devices, or when the biological information measuring device is changed due to a failure of the biological information measuring device or a change to a new model.

  When the device name management unit 122 receives a device name management instruction and data to be managed from the data collector control unit 125, the device name management unit 122 executes device name management processing. Data to be managed is composed of two pieces of data, that is, a user device name and an identification address. FIG. 6 shows a flow of device name management processing. The device name management process includes a step S601 for searching for a user device name, a step S602 for confirming the presence / absence of the device name, a step S603 for creating the device name management data 500, and a step S604 for storing the device name management data 500. Step S605 for returning the management instruction result, Step S606 for confirming whether or not the identification addresses match, and Step S607 for updating the device name management data 500.

  The contents of the device name management process will be described below. In step S601 for searching for a user device name, a search is made from the user device name 512 of the device name management data 500 managed by the device name management unit 122 for a match with the device name for which the management instruction has been issued.

  In step S602 for confirming the presence / absence of a device name, the process branches depending on the presence / absence of matching data based on the result of the search in step S601. If there is no matching data, the process proceeds to step S603 for creating the device name management data 500. If there is matching data, the process proceeds to step S606 to check whether the identification addresses match.

  In step S603 for creating the device name management data 500, the device name management data 500 is newly created from the data to be managed. After the creation, the process proceeds to step S604 in which the device name management data 500 is stored.

  In step S606 for confirming whether or not the identification addresses match, the related identification address information ID 521 is acquired from the user device name 512 that has been matched in step S602, and the identification address 523 is extracted. The extracted identification address 523 determines whether or not there is data matching the identification address for which the management instruction has been issued. If there is no matching data, the process proceeds to step S607 where the device name management data 500 is updated. To do. If there is matching data, the device name management process ends as an exception, and the process proceeds to step S605 in which a management instruction result is returned.

  In step S607 for updating the device name management data 500, the device name management data 500 of the user device name 512 searched in step S601 is updated. The device name management data 500 is updated by changing the registration number 522 of the identification address data 520 of the device name management data 500 and adding the identification address for which the management instruction has been given to the identification address 523. After the update, the process proceeds to step S604 in which the device name management data 500 is stored.

  In step S604 for storing the device name management data 500, the device name management data 500 created in step S603 or the device name management data 500 updated in step S607 is stored in a storage area. If the storage ends normally, it is determined that the device name management process has ended normally, and the process proceeds to step S605 in which a management instruction result is returned. If the storage ends abnormally, it is determined that the device name management process has ended abnormally, and the process proceeds to step S605 where the management instruction result is returned.

  In step S605 of returning the management instruction result, the management instruction result indicating the processing result of the device name management process is returned to the data collector control unit 125. The management instruction result is one of normal end, abnormal end, and exception end. A parameter is added to each management instruction result. The parameter for normal termination is the stored device name management ID. The abnormal termination parameter is an ID indicating the cause of the abnormal termination. The exception termination parameter is an ID indicating the exception termination. The above is the contents of the device name management process.

  The device name management unit 122 executes device name reference processing when receiving a device name reference instruction and data to be referred to from the data collector control unit 125. The data to be referred to is composed of two pieces of data of a user device name and an identification address. In the device name reference process, a user device name 512 and an identification address 523 that match the data to be referred to are searched from the device name management data 500 managed by the device name management unit 122, and the reference process result is controlled by the data collector. Reply to part 125.

  As a result of the reference process, the user device name 512 and the identification address 523 both match, the user device name 512 matches only, the user device name matches only, the identification address match matches only the identification address 523, and the user device name 512 matches. There is a need to classify the four types, i.e., a mismatch that does not match both of the identification address 523 and the identification address 523.

  The data management unit 123 includes a rewritable storage area. The storage area is secured by an HDD, a flash ROM, an EEPROM, or the like. Further, it may be secured on a removable memory represented by an SD card. In that case, it is necessary to provide the portable data collector 120 with a dedicated interface for accessing the memory to be used. Further, the device name management unit 122 may use an existing database for device name management. When a database is used, device name management is performed at high speed. However, since a large amount of memory is used in the portable data collector, is the database used based on the overall memory usage capacity? It is good to judge. Further, it is preferable to share a portion that can be shared with the device name management unit 122. FIG. 7 shows measurement result management data 700 for one device name. The measurement result management data 700 includes device measurement result data 710 and measurement result data 720 that is associated with the device measurement result data 710. Next, detailed contents of the measurement result management data 700 will be described.

  The device measurement result data 710 is data in which measurement result information is associated with one device name. The device measurement result data 710 is data management that is an ID for management by the data management unit 123 in two elements: a device name management ID 511 and a measurement result information ID 721 indicating a measurement result of the biological information measuring device 110. It consists of three elements with ID711.

  The measurement result data 720 is data that manages the received measurement results. The measurement result data 720 includes device measurement result data in three elements: a data management ID 711, a measurement result number 722 that is the number of measurement results to be managed, and a plurality of measurement results 723 corresponding to the measurement result number 722. It consists of four elements with a measurement result information ID 721 that is an ID to be associated with 710.

  By configuring the device measurement result data 710 with the device measurement result data 710 and the measurement result data 720, a plurality of measurement results 723 can be managed for one device name. Therefore, when managing the measurement results 723 for the same device name, it is sufficient to update the number of measurement results 722 and add the measurement results 723. Further, the measurement result 723 can be searched using the device name management ID 511 searched from the identification address of the biological information measuring device 110.

  The data management unit 123 requires data management processing. The data management process is executed when a data management instruction and data management data are received from the data collector control unit 125. Data for data management is a device name management ID 511 and a measurement result to be managed. There may be a plurality of measurement results to be managed at the same time. Since a plurality of measurement results exist at the same time, the measurement result to be managed may be composed of two elements, the number of measurement results to be managed and the measurement results corresponding to the number.

  The data management process searches the managed measurement result management data 700 for a device name management ID 511 that matches the device name management ID of the data management data. As a result of the search, if there is no matching device name management ID 511, new measurement result management data 700 is created and stored in the storage area. If a matching device name management ID 711 exists, the measurement result data 720 is updated and stored in the storage area.

  The command generation unit 124 generates a command for sending an instruction to the biological information measuring device 110 in wireless communication. At least two commands can be generated. The two commands are the device name change command 402 and the measurement result request command 401 described above. The command generation unit 124 includes a device name change command generation unit 127 and a measurement result request command generation unit 128 that are generation units of each command. Further, the command generation unit 124 is connected to the user input unit 126 in order to set a device name.

  When receiving the device name change instruction from the data collector control unit 125, the command generation unit 124 transmits an execution instruction to the device name change command generation unit 127. Further, when a measurement result request instruction is received from the data collector control unit 125, an execution instruction is transmitted to the measurement result request command generation unit 128.

  When the device name change command generation unit 127 receives an execution instruction from the command generation unit 124, the device name change command generation unit 127 transmits an input reception start instruction to the user input unit 126. Then, it waits for reception of a value input from the user input unit 126. When the value input from the user input unit 126 is received, it is confirmed whether or not the device name naming rule is met. When the device name naming rule is met, the value received from the user input unit 126 is set in the command parameter 420. Further, “CH” indicating the device name change command 402 is set in the command identifier 410. As described above, the device name change command 402 is generated. Ignored if the device naming convention is not met. Further, the generated device name change command 402 is transmitted to the second wireless communication unit 121, and is transmitted from the second wireless communication unit 121 to the biological information measuring device 110.

  When the measurement result request command generation unit 128 receives the execution instruction from the command generation unit 124, the measurement result request command generation unit 128 transmits an input reception start instruction to the user input unit 126. Then, it waits for reception of a value input from the user input unit 126. When the value input from the user input unit 126 is received, the received value is set in the command parameter 420 as the result request parameter 421. Thereby, the user can arbitrarily set the transmission method of the measurement result. Further, “RD” indicating the measurement result request command 401 is set in the command identifier 410. Thus, the measurement result request command 401 is generated. In addition, the measurement result request command 401 is transmitted to the second wireless communication unit 121 and transmitted from the second wireless communication unit 121 to the biological information measuring device 110.

  When the data collector control unit 125 receives the device name and identification address of the biological information measuring device 110 received from the first wireless communication unit 121, the data collector control unit 125 starts processing. FIG. 8 shows a flow of the data collector control unit 125. The data collector control unit 125 executes step S801 for analyzing the device name, step S802 for selecting the device, step S803 for branching to analysis-specific processing, step S804 for executing the change mode, and the measurement result acquisition mode. Step S805, step S806 for confirming the measurement result, step S807 for managing the measurement result, and warning mode S808.

  In step S801 of analyzing the device name, the device name management unit 122 is linked to perform analysis based on the received device name and identification address. FIG. 9 shows a more detailed processing flow of step S801 for analyzing the device name. The step S801 for analyzing the device name includes a step S901 for confirming the device name, a step S902 for confirming registration of the device name and the identification address, and a step S903 for setting a discrimination flag.

  The contents of device name analysis will be described below. In step S901 for confirming the device name, it is confirmed whether or not the received device name is an initial device name. If it is the initial device name, the received device name is transferred to step S902 as the initial device name. If it is not the initial device name, it is further confirmed whether or not the received device name corresponds to the device name naming rule. If the device name naming rule is supported, the received device name is transferred to step S902 as the user device name. If the device name naming rule is not supported, the process proceeds to step S903 as an unsupported device name. Through the above step S901, it is determined whether the device name is an initial device name, a user device name, or an unsupported device name.

  In step S902 for confirming registration of the device name and identification address, the data collector control unit 125 transmits a device name reference instruction and data to be referenced to the device name management unit 122, and the data collector control unit 125 The reference processing result from the management unit 122 is received. The result of the reference process is as follows. If the device name is registered and the identification address is also registered, all matches. If the device name is registered and the identification address is not registered, the user device name matches. If the device name is not registered and the identification address is registered, the identification address matches. If the device name is not registered and the identification address is not registered, they do not match. When the received device name is the initial device name, the initial device name is not managed by the device name management unit 122, and therefore the device name is not registered.

  In step S903 for setting the determination flag, the result determined in steps S901 and S902 is set in the determination flag. Table 2 shows the setting of the discrimination flag. There are a total of seven setting values for the determination flag, and the seven types can be classified.

  The case where the determination flag is set to “1” is a case where it is determined in step S901 that the device name is not supported.

  When the determination flag is set to “2”, the device name is the initial device name, the device name is not registered, and the identification address is not registered.

  When the determination flag is set to “3”, the device name is the initial device name, the device name is not registered, and the identification address is registered.

  When the determination flag is set to “4”, the device name is the user device name, the device name is registered, and the identification address is not registered.

  When the determination flag is set to “5”, the device name is the user device name, the device name is registered, and the identification address is registered.

  When the determination flag is set to “6”, the device name is the user device name, the device name is not registered, and the identification address is not registered.

  When the determination flag is set to “7”, the device name is the user device name, the device name is not registered, and the identification address is registered.

  In step S801 for analyzing the device name, after the analysis is completed, the received device name and identification address are transmitted to the display unit 220 as display contents. If the determination flag is “1” and the device name is not supported, it is not transmitted to the display unit 220. Furthermore, step S801 is executed by the number of received device names and identification addresses of the biological information measuring device 110 received from the first wireless communication unit 121. That is, step S801 is performed by the number of biological information measuring devices 110 that can be retrieved from the portable data collector 120 by wireless communication. The display unit 220 displays as many device names and identification addresses as the number of analysis results in step S801.

  In step S802 of selecting a device, an input acceptance start instruction is transmitted to the user input unit 126. The user input unit 126 can select the device name displayed on the display unit 220 in step S801. When the value of the selected device name is received from the user input unit 126, the biological information measuring device 110 having the selected device name and the second wireless communication unit 121 establish communication. And step S803 which branches to the process according to analysis is performed.

  In step S803 that branches to the analysis-specific process, the process to be executed is branched from the value of the determination flag for the selected device name received in step S802. If the value of the discrimination flag is “1”, the device name is not supported and is ignored. When the value of the determination flag is “2”, the process proceeds to step S804 in which the change mode is executed. When the value of the determination flag is “4” to “6”, the process proceeds to step S805 in which the measurement result acquisition mode is executed. When the value of the determination flag is “3” or “7”, the process proceeds to step S808 for executing the warning mode.

  In step S804 of executing the change mode, a device name change instruction is transmitted from the data collector control unit 125 to the command generation unit 124. Thereafter, the result of the device name change returned from the biological information measuring device 110 is awaited. When the device name change result is received from the second wireless communication unit 121, it is confirmed whether or not the device name can be changed normally. If the device name has been changed normally, the process proceeds to step S805 in which the measurement result acquisition mode is executed. If the device name has not been changed normally, step S804 is executed again. Re-execute up to three times.

  In step S805 of executing the measurement result acquisition mode, a measurement result request instruction is transmitted from the data collector control unit 125 to the command generation unit 124. And it transfers to step S806 which confirms a measurement result.

  In step S806 for confirming the measurement result, reception of the measurement result, which is the execution result of step S805 transmitted from the biological information measuring device 110, is executed. It is assumed that if the measurement result is not received from the second wireless communication unit 121 within the time specified in advance, the measurement result cannot be acquired normally. When the measurement result is received from the second wireless communication unit 121 within the time specified in advance, step S807 for managing the result is executed.

  In step S807 for managing the result, since the measurement result has been successfully received, the management of the device name and the management of the measurement result are executed. Data managed by the device name management unit 122 is created from the device name and identification address selected in step S802, and the created management data is transmitted to the device name management unit 122 together with the management instruction. When the management instruction result is received from the device name management unit as a result of the management instruction, the management instruction result is analyzed. If the analysis results in abnormal termination or exception termination, a parameter indicating the content at that time is transmitted as display content to the display unit 220, and the data collector control unit 125 terminates the processing. If the result of the analysis is normal end, the device name management ID is extracted from the normal end parameters. The management data of the data management unit 123 is created from the extracted device name management ID and the received measurement result, and the management instruction is transmitted to the data management unit 123 together with the created management data, and the data collector control unit 125 ends the process.

  In step S807 for executing the warning mode, there is a content to be noted between the information registered in the device name management unit 122 and the information of the biological information measuring device 110, so the warning content is displayed as the display content to the display unit 220. Then, the data collector control unit 125 ends the process. The above is the description of the portable data collector 120.

  The portable data collector 120 may be a PDA, notebook computer, or cellular phone having the above functions, and is not limited to these as long as it is a portable terminal having a display device, an input device, and a wireless communication device. .

  Next, processing according to the relationship between the biological information measuring device 110 and the plurality of portable data collectors 120 will be described. FIG. 10 shows a process for registering device names in a plurality of portable data collectors 120. An example in which there are two portable data collectors 120 (a portable data collector 120a and a portable data collector 120b) and one newly added biological information measuring device 110d is shown.

  When the portable data collector 120a searches for a device capable of wireless communication in step S1001, the biological information measuring device 110d executes step S1002 in which a device name is transmitted from the biological information measuring device 110d as a response to the search.

  In step S1002 for transmitting the device name, the biological information measuring device 110d transmits the device name and the identification address to the portable data collector 120a. Since the biological information measuring device 110d communicates with the portable data collector 120 for the first time, the device name of the biological information measuring device 110d at this time is the initial device name because it has not been changed.

  The portable data collector 120a displays the received device name and identification address on the display unit 220 after executing step S1003 for analyzing the device name. At this time, if there is a response from a plurality of devices other than the biological information measuring instrument 110d, the device name is analyzed for all devices, and after step S1003, the device is received if it is to be displayed. The device name and identification address are displayed on the display unit 220. Then, step S1004 for selecting a device is executed, and the biological information measuring device 110d is selected from the displayed contents.

  After selecting the biological information measuring device 110d in step S1004 for selecting a device, the portable data collector 120a executes step S1005 for executing the change mode. As a result, the user device name, which is a new device name, is transmitted as the device name change command 402 to the biological information measuring device 110d.

  Upon receiving the device name change command 402, the biological information measuring device 110d executes step S1006 for changing the device name. As a result, the biological information measuring device 110d changes the device name to the transmitted user device name.

  When the change of the device name of the biological information measuring device 110d is normally completed, the portable data collector 120a executes step S1007 for executing the measurement result acquisition mode, and receives the measurement result from the biological information measuring device 110d. To do. On the other hand, the biological information measuring device 110d executes Step S1008 for transmitting the measurement result to the portable data collector 120a. If the measurement result can be normally received from the biological information measuring device 110d, in step S1009 for managing the measurement result, the measurement result received in step S1007 and the user device name changed in step S1005 are stored.

  Subsequently, in step S1010, when portable data collector 120b searches for a device capable of wireless communication, biological information measuring device 110d executes step S1011 in which a device name is transmitted from biological information measuring device 110d as a response to the search.

  In step S1011 for transmitting the device name, the biological information measuring device 110d transmits the device name and the identification address to the portable data collector 120b. Since the biological information measuring device 110d has already communicated with the portable data collector 120 and the device name has been changed, the device name at this time is the user device name changed in step S1006.

  The portable data collector 120b displays the received device name and identification address on the display unit 220 after executing step S1012 for analyzing the device name. At this time, if there is a response from a plurality of devices other than the biological information measuring device 110d, the device name is analyzed for all devices, and after step S1012 is executed, the device is received if it is a device to be displayed. The device name and identification address are displayed on the display unit 220. And step S1013 which selects a device is performed, and the biometric information measuring device 110d is selected from the displayed content.

  Since the device name of the biological information measuring device 110d selected in step S1013 for selecting a device is the user device name, the portable data collector 120b does not execute the change mode and executes step S1014 in which the measurement result acquisition mode is executed. Execute. In response to this, the biological information measuring device 110d executes Step S1015 of transmitting the measurement result to the portable data collector 120b. If the measurement result can be normally received from the biological information measuring device 110d, the measurement result received in step S1014 and the received user device name are stored in step S1016 for managing the measurement result.

  In the biological information collection system of the first embodiment described above, when the biological information measuring device 110 receives a device name change command from the portable data collector 120, the device name of the biological information measuring device 110 is set. Since the device name changing unit 115 is provided and the measured biometric information and the changed device name are associated with each other and transmitted to the portable data collector 120, convenience is improved.

  That is, by setting the device name of the biological information measuring device 110 to the user device name according to the device name naming rule, the user of the biological information collecting system 100 can discriminate the biological information measuring device 110. The biological information measuring instrument 110 can be easily identified. .

  Furthermore, in the biometric information collection system according to the first embodiment, the user device name is displayed on the display unit 220 of the portable data collector 120 and displayed as a search result of devices that the portable data collector 120 can wirelessly communicate with. Since the biological information measuring device 110 to be connected is selected from the list, the biological information as the measurement result can be acquired from the biological information measuring device 110 desired by the user of the biological information collecting system.

  Furthermore, in the biometric information collection system of the first embodiment, the device name of the biometric information measuring device 110 to be newly added is changed to the user device name by the portable data collector 120 connected first, and then connected. The portable collector 120 that uses the changed user device name allows the target biological information based on the registered device names (user device names) among the plurality of portable data collectors 120. A measuring instrument can be identified.

  The biological information collecting system according to the present invention has a feature that can easily specify a target biological information measuring device, and is used in an environment where a plurality of biological information measuring devices and a plurality of portable data collectors are mixed.
